Matsunaga, Tomoya Kon, M. Washio, K. Shinozawa, T. Ishikiriyama, M. 2008-12-23 High-pressure metal hydride (MH) tank is a possible hydrogen storage system for fuel cell vehicles. The merit of the high-pressure MH tank system is improved by the use of a metal hydride with high dissociation pressure. In this study, TiCrV and TiCrVMo alloys with BCC structure has been developed for the high-pressure MH tank system. The developed TiCrVMo alloy shows 2.4 mass% of effective hydrogen capacity between 0.1 MPa and 33 MPa at 298 K, which has a dissociation pressure of 2.3 MPa at 298 K. By investigating the dissociation pressures of the synthesized metal hydrides, it is found that Mo has a special effect to increase dissociation pressure of the metal hydrides. This effect is probably attributed to the large bulk modulus of Mo compared to other elements. application/pdf https://folia.unifr.ch/global/documents/301250 https://folia.unifr.ch/documents/301250/files/matsunaga_tah.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.ijhydene.2008.11.061 info:eu-repo/semantics/openAccess License undefined International Journal of Hydrogen Energy. - 2009, vol. 34, no. 3, p. 1458-1462 Metal hydrides Bcc alloys Thermodynamic properties PC isotherms info:eu-repo/classification/udc/53 TiCrVMo alloys with high dissociation pressure for high-pressure MH tank http://purl.org/coar/resource_type/c_6501
